The upwind rainfall detection system at Metcheck is a little bit more than that.

This page will look up to 20km upwind from your current location and show you not only the intensity of any rain, sleet or snow heading your way but the time it is expected.

The scanning radar below will show you all the detected rain, sleet or snow in a 20x20km radius around your location so that you know if there are showers or precipitation in your vicinity. Data is updated automatically every 5 mins and the page is refreshed for you.
